All releases of Lua

Release Notes: This release adds better handling of string collisions based on a random seed. This work version is meant to let the community assess the usefulness and the effectiveness of this experimental feature.

Release Notes: This is the first major version since 2006. It adds yieldable pcall and metamethods, a new lexical scheme for globals, ephemeron tables, a new library for bitwise operations, light C functions, an emergency garbage collector, a goto statement, and finalizers for tables.

Release Notes: Changes since rc4: 'table.pack' returns 'n' too; clarifications between 'deprecated' and 'removed'; a fix for a compilation error in 'luai_apicheck' with LUA_USE_APICHECK; removal of an incorrect assert in lparser.c; and reordering of some defines in lua.h.
